Description
»Verbindung von Teilen mit kreisförmigem Querschnitt»»Connection of parts with a circular cross-section»
Die vorliegende Erfindung bezieht sich auf eine Verbindungsvorrichtung und insbesondere auf ein Verbindungsstück für Teile mit kreisförmigem Querschnitt.The present invention relates to a connector and in particular to a connector for parts with a circular cross-section.
Es ist in vielen Fällen zur Erzielung einer guten Gesamtansicht und zur Verbesserung der strukturellen Verkettung von Teilen, besonders von Teilen verschiedener physikalischer Eigenschaften, wünschenswert, ein starres Teil, beispielsweise aus einem zumindest mäßig wärmebeständigem Material, mit einem anderen Teil oder einer Vorrichtung mit thermoplastischen Eigenschaften in einfacher, preisgünstiger Weise zu verbinden. Wie anhand einer speziellen Ausführungsform der vorliegenden Erfindung erläutert, handelt es sich beispielsweise darum, ein ringförmiges Teil auf das ringförmige Vorderende eines thermoplastischen Zylinderkäfigs oder Behälters aufzusetzen, wobei letztere durch eine Öffnung in einer Frontplatte oder ein starres Armaturenbrett ragen. Dabei ist das ringförmige Teil aus schimmerndem Metall angefertigt, während es sich beim Zylinderkäfig um einen dunklen, thermoplastischen Kunststoff handelt. In den bisher bekannten Verfahren zur Verbindung derartiger Teile wird der Kunststoff in einer Form ausgeformt 9 die das starre Metallteil als Einsatz enthält, sodaß bei der Verbindung der Teile der Kunststoff in Vertiefungen oder andere eine Verknüpfung der Teile bewirkende Abschnitte einfließt. Heben seiner Kostspieligkeit ist dieses Verfahren dadurch wenig vorteilhaft, daß das Kunststoffteil nur mit dem in ihm eingebetteten Metallteil verwendet werden kann. Gemäß der vorliegenden Erfindung kann das Kunststoffteil in vielen Fällen ■ so ausgeformt werden, daß es mit oder ohne dem Metallteil verwendet werden kann, besonders wenn letzteres nur zur Verzierung dient. Auch werden der AusformungsVorgang und die Form erfindungsgemäß vereinfacht, da keine Maßnahmen zum Einsetzen des Metallteils vorgesehen werden müssen.In many cases, in order to achieve a good overall view and to improve the structural interlinking of parts, especially parts with different physical properties, it is desirable to have a rigid part, for example made of at least a moderately heat-resistant material, with another part or a device with thermoplastic properties to connect in a simple, inexpensive way. As explained with reference to a specific embodiment of the present invention, it is, for example, a question of placing an annular part on the annular front end of a thermoplastic cylinder cage or container, the latter protruding through an opening in a front panel or a rigid dashboard. The ring-shaped part is made of shimmering metal, while the cylinder cage is a dark, thermoplastic material. In the previously known method for connecting such parts, the plastic is formed in a mold 9 which contains the rigid metal part as an insert, so that when the parts are connected, the plastic flows into depressions or other sections causing the parts to be linked. Besides its cost, this method is not very advantageous in that the plastic part can only be used with the metal part embedded in it. According to the present invention, the plastic part can in many cases be shaped so that it can be used with or without the metal part, especially if the latter is only used for decoration. The shaping process and the shape are also simplified according to the invention, since no measures for inserting the metal part have to be provided.

In der dargestellten Ausführungsform der Erfindung handelt es sich bei dem Metallteil um ein an der Außenseite angebrachtes Teil, das den thermoplastischen Teil fest umschließt, Wie jedoch dem Fachmann aus den folgenden Ausführungen sofort ersichtlich, können die Rollen der beiden Teile vertauscht sein. In der beschriebenen Ausführungsform ist das ringförmige Metallteil ferner mit mehreren ringförmigen Vertiefungen an seiner Innseite versehen, deren Durchmesser abnimmt und die jeweils voneinander durch ringförmige Nocken von abnehmendem Innendurchmesser getrennt, sind* Die Innenseite des ringförmigen Teils ist damit am Innenumfang gezahnt und ergibt eine im wesentlichen konische Gesamtfläche. Die ringförmigen Kammabschnitte haben vorzugsweise scharfen V-förmigen Querschnitt, wie in den Figuren dargestellt. Wie ferner aus den Figuren ersichtlich, ist der am MeGallteil anliegende Abschnitt des thermoplastischen Kunststoffteils so ausgebildet, daß er sich zunächst leicht teilweise in das Metallteil mit seinen ringförmigen Kämmen einsetzen läßt, Das vordere Ende des Kunststoff teils ist dazu, an seinem Umfang abgeschrägt und außerdem in Durchmes.verrichtung leicht "verjüngt, z.B. unter einem Winkel von 5° abgeschrägt.In the illustrated embodiment of the invention acts the metal part is a part attached to the outside that tightly encloses the thermoplastic part, However, as is immediately apparent to a person skilled in the art from the following statements, the roles of the two parts can be interchanged be. In the embodiment described, the annular metal part is further provided with a plurality of annular recesses its inner side, the diameter of which is decreasing and each of which is separated from one another by annular cams of decreasing Inside diameter separated, are * The inside of the annular Part of it is thus toothed on the inner circumference and results in an essentially conical overall surface. The annular ridge sections preferably have a sharp V-shaped cross-section, as shown in the figures. As also from the figures the section of the adjacent to the MeGall part can be seen thermoplastic plastic part formed so that he at first can be easily inserted partially into the metal part with its annular combs, the front end of the plastic partly to it, beveled at its circumference and moreover slightly "tapered in diameter, e.g. under a 5 ° beveled angle.
Die beiden Teile werden an. ihren Verbindungsflächen mit einander verkoppelt durch Anlegen entsprechender Kräfte, die ein Teil in Achsrichtung in aas andere schieben. Dabei wird gleichzeitig Schwingungsensrgie, z.B. von einem elektromechanischen Ultraschall-übertrager, dem Metallteil zugeführt. Die Kraft und die Ultraschal!energie bleiben wirksam, bis die beiden Teile im gewünschten Ausmaß miteinander verbunden sind. Während des Zusammenschieben^ wird ein außenseitiger, ringförmiger Abschnitt des Kunststoffteils in der Nähe der Berührungsfläche mit dein Metallteil durch mechanische Einwirkung aufgeheizt und fließt unter der Wirkung der an die Teile angelegten Kräfte teilweise um und über die kreisförmigen Kammab-The two parts are going to. their interfaces coupled with each other by applying appropriate forces that push one part in the axial direction into the other. Included at the same time vibrations, e.g. from an electromechanical Ultrasonic transmitter, fed to the metal part. The force and the ultrasonic energy remain effective until the both parts are connected to each other to the desired extent. During the pushing together, an outer, ring-shaped Section of the plastic part near the contact surface with your metal part heated by mechanical action and flows under the action of the applied to the parts Forces partially around and over the circular crest

schnitte und in die Vertiefungen zwischen denselben. Das Weiterfließen des Kunststoffs führt schließlich zur Auffüllung der Vertiefungen, und die Teile werden dadurch genügend verstärkt, um den mechanischen Anforderungen zu entsprechen. Nach dem Einsetzen und Zusammenfügen der Teile wird die Ultraschallenergie abgeschaltet und der vorübergehend erweichte, thermoplastische Abschnitt des Kunststoffteils härtet in den Vertiefungen der Metallteils aus, wodurch eine feste Verbindung zwischen den beiden Teilen geschaffen wird. Der ganze Vorgang läßt sich leicht in kurzer Zeit durchführen, z.B. in etwa 2 Sekunden im Falle eines Rings mit 2,5 cm Durchmesser, auf den sich das folgende, unter Bezugnahme auf die Figuren beschriebene Ausfülirungsb ei spiel bezieht.cuts and into the indentations between them. If the plastic continues to flow, it will eventually fill up the depressions, and the parts are strengthened enough to meet the mechanical requirements. To When the parts are inserted and joined together, the ultrasonic energy is switched off and the temporarily softened, thermoplastic one The section of the plastic part hardens in the recesses of the metal part, creating a firm connection is created between the two parts. The whole process can easily be carried out in a short time, e.g. in about 2 Seconds in the case of a 2.5 cm diameter ring, which is described below with reference to the figures Fulfillment example refers to.

Das in Figuren 1 und 2 dargestellte Teil aus thermoplastischem Kunststoff hat die Form einer ringförmigen Hülse 10 mit einem flanschartigen, ringförmigen Kantenabschnitt 1Or, dessen hintere Fläche 1Of an der gestrichelt angedeuteten Frontplatte P anliegt.

gesehen nach hinten verläuft. Die Figuren zeigen ferner ein Metallteil 12 in der Form eines Zierrings mit einem nach innen gebogenen Flansch 12f und einer nach hinten verlaufenden, ringförmigen Außenkante 12r, deren ringförmige Innenfläche so ausgebildet ist, daß mehrere scharfe, ringförmige Erhebungen mit dazwischenliegenden Vertiefungen entstehen. Der Durchmesser der ringförmigen Erhebungen und Vertiefungen nimmt von der Rückseite der Hülse aus gesehen allmählich ab. Die Vorderseite des Metallteils 12 ist in Figur 3 dargestellt, während Figur 4 die Außenkante 12r vor dem Zusammensetzen mit der thermoplastischen Außenkante 1Or der Hülse 10 darstellt. Figur 5 zeigt in stark vergrößertem Maßstab Abschnitte des Metallteils 12 und der thermoplastischen Hülse 10 beim Vereinigen der beiden Teile durch Anlegen entgegengesetzter Kräfte F und F'. Diese Kräfte werden an der Peripherie der zusammenzufügenden Teile angelegt. Die zum Anlegen der Druckkräfte verwendeten Vorrichtungen können sehr verschiedener Art sein, je nach der Beschaffenheit der zusammenzufügenden Teile. Im Falle' der dargestellten Teile wird Kantenabschnitt 1Or auf einen ortsfesten, halternden Amboß aufgesetzt, der eine Gegenkraft F' zur Kraft F ausübt, die durch eine Presse über einen mit Ultraschall schwingenden Kopfabschnitt an Außenkante 12r angelegt wird, während dieselbe auf Kantenabschnitt 10r aufgesetzt wird. Wenn die im Innern ringförmig geriffelte Oberfläche der Außenkante 12r den Außenabschnitt des sich ringförmig verjüngenden Endteils 1Or aufnimmt, wird der erste Kamm R1 zunächst als genau passendes Hindernis getroffen. Durch die Ultraschallerregung der Außenkante 12r wird Hitze an den Berührungspunkten der beiden Teile längs des Kamms R1 erzeugt, die Berührungspunkte und deren Nachbarabschnitte am Kantenabschnitt 1Or werden erweicht und plastisch, und Außenkante 12r schiebt sich über Kantenabschnitt 1Or. Das im äußerenseen backwards. The figures also show a metal part 12 in the form of a decorative ring with an inside curved flange 12f and a rearwardly extending, annular outer edge 12r, the annular inner surface is designed so that a plurality of sharp, annular elevations with intervening depressions arise. Of the The diameter of the annular bumps and depressions gradually decreases as seen from the rear of the sleeve. the The front of the metal part 12 is shown in FIG. 3, while FIG. 4 shows the outer edge 12r before being assembled with represents the thermoplastic outer edge 1Or of the sleeve 10. FIG. 5 shows sections on a greatly enlarged scale of the metal part 12 and the thermoplastic sleeve 10 when the two parts are combined by applying opposite ones Forces F and F '. These forces are on the periphery of the parts to be joined. The one to apply the compressive forces The devices used can be of very different types, depending on the nature of the parts to be joined. In the case of the parts shown, the edge section 1Or is placed on a stationary, holding anvil, which creates a counterforce F 'exerts a force F which is applied to the outer edge 12r by a press via a head section oscillating with ultrasound while being placed on edge portion 10r. When the inside ring-shaped corrugated surface the outer edge 12r receives the outer portion of the annular tapered end portion 1Or, becomes the first Comb R1 hit first as a precisely fitting obstacle. The ultrasonic excitation of the outer edge 12r generates heat generated at the points of contact of the two parts along the ridge R1, the points of contact and their neighboring sections on Edge portion 1Or is softened and plasticized, and outer edge 12r slides over edge portion 1Or. That on the outside

ringförmigen Abschnitt enthaltene, erweichte thermoplastische Material fließt um und von Kamm R1, bis Kamm R2 als nächstes Hindernis getroffen wird. Die Menge des hinter R1 verbliebenen Materials ist gering und die bei diesem Vorgang geschaffene Vertiefung ist damit flach. Weiteres Material wird dann durch Berührung mit Kamm 2 erweicht, sodaß Kantenabschnitt 1Or weiter in den Raum innerhalb des Metallteils 12 eingeschoben werden kann. Der im Vergleich zu Kamm R1 verringerte Innendurchmesser des Kamms R2 bestimmt die Menge des nach außen gedrückten Plastikmaterials, das Vertiefung V1 auffüllt. Beim weiteren Zusammenschieben der Teile trifft Kantenabschnitt 1Or auf Vorsprung S1 am Metallteil 12, und da der Innendurchmesser des Metallteils an dieser Stelle verringert ist, findet beim weiteren Erhitzen plastischer Fluß des an Kantenabschnitt 1Or enthaltenen Materials in die zweite ringförmige Vertiefung V2 statt. Diese Vorgang hält an, bis die Einwirkung der Kräfte und die ültraschallvibrationen der Außenkante 12r abgebrochen werden, oder wenn Kantenabschnitt 1Or die Innenfläche des nach innen gebogenen Flansche 12f berührt. Zu diesem Zeitpunkt sind dann Vertiefungen V1 und V2 mit plastisohem Kunststoff aufgefüllt, und nach Beendigung der Ultraschall- und Krafteinwirkung kühlt der Kunststoff ab und härtet aus. Die Teile werden auf diese Weise miteinander verbunden, können sich nicht ohne völlige Zerstörung der Anordnung trennen, und können sich vor allem nicht mehr in achsialer Richtung gegeneinander verschieben·Annular section containing softened thermoplastic material flows around and from crest R1, to crest R2 next Obstacle is hit. The amount of material left behind R1 is small and that created in this process The recess is thus flat. Further material is then softened by contact with comb 2, so that edge section 1Or can be pushed further into the space within the metal part 12. The reduced inner diameter compared to comb R1 of the comb R2 determines the amount of plastic material pressed outwards, which fills well V1. At the further pushing the parts together hits the edge section 1Or on projection S1 on the metal part 12, and since the inner diameter of the metal part is reduced at this point upon further heating, plastic flow of the material contained at the edge portion 1Or into the second annular one Specialization V2 instead. This process continues until the action of the forces and the ultrasonic vibrations of the outer edge 12r or when edge portion 1Or contacts the inner surface of the inwardly bent flange 12f. To this Point in time are then wells V1 and V2 with plastisohem Filled with plastic, and after the end of the ultrasound and force, the plastic cools down and hardens. The parts can be connected to each other in this way do not separate without complete destruction of the arrangement, and above all can no longer separate in the axial direction move against each other
Die beiden Teile können so miteinander verbunden werden, daß sie nicht mehr ohne Zerstörung mindestens, eines Teils voneinander getrennt werden können. Es kann aber in gewissen Anwendungsfällen zweckmäßig sein, die Möglichkeit einer Verdrehung der Teile gegeneinander zuzulassen, 'flenn die abschnittsweise konischen, ringförmigen Innenflächen der Außenkante 12r glatt sind und das thermoplastische Material des Kantenab,-The two parts can be connected to one another in such a way that they can no longer be separated from one another without destroying at least one part. In certain applications, however, it can be useful to allow the parts to be rotated against each other, if the partially conical, ring-shaped inner surfaces of the outer edge 12r are smooth and the thermoplastic material of the edges is

Schnitts 1Or selbstschmierend und abriebsfrei ist, wie beispielsweise Teflon oder Fylon, kann ein Verdrehen der Teile gegeneinander stattfinden. Wenn andererseits das thermoplastische Kunststoffmaterial Glasfasern oder kornartige Teilchen . in genügenden Mengen enthält, ergibt sich eine Reibungswirkung, die ein Verdrehen der beiden Teile gegeneinander unmöglich macht, es sei denn mindestens eines der Teile wird dabei zerstört. Ein Verbinden der Teile mit Drehungsblockierung kann durch zusätzliches Aufrauhen der Innenflächen der Außenkante 12r erzielt werden. Falls eine ausgezeichnete Blockierungswirkung erreicht werden soll, können Kerben in den Kanten der Kämme angebracht werden. Der Widerstand gegen Verdrehen der beiden miteinander verbundenen Teile kann eingestellt werden durch geeignete Wahl der Menge oder der Art eines dem thermoplastischen Kunststoff zugegebenen Füllmittels, sodaß die bei Bewegung des Kantenabschniuts TOr auftretende Reibung auf den gewünschten Wert eingestellt wird«. Größere Mengen scharfkantiger Schleifmittelf wie z.B. Sand, Siliziumkarbid und dergleichen ergeben eine sehr starke Sperrwirkung für Drehbewegungen, besonders wenn die Kämme zusätzlich aufgerauht oder mit Kerben versehen werden« Abgerundete Teilchen eines dem Kunststoff zugegebenen Füllstoffs ermöglichen andererseits, je nach Art und Menge, eine gewisse Verdrehung. In all diesen Fällen können die Teile aber nioho gegeneinander in aehsialer Richtung verschoben werden.Schnitts 1Or is self-lubricating and non-abrasive, such as Teflon, or Fylon, can twist the parts take place against each other. On the other hand, when the thermoplastic resin material is glass fiber or granular particles. contains in sufficient quantities, there is a frictional effect that a twisting of the two parts against each other is impossible unless at least one of the parts is destroyed. A connection of the parts with rotation lock can can be achieved by additionally roughening the inner surfaces of the outer edge 12r. If an excellent blocking effect is to be achieved, notches can be made in the edges of the combs. Resistance to twisting the both the interconnected parts can be adjusted by appropriately selecting the amount or kind of one of the thermoplastic Plastic added filler, so that the friction that occurs when the edge portion TOr moves the desired value is set «. Larger amounts of sharp-edged Abrasives such as sand, silicon carbide and the like result in a very strong blocking effect for rotary movements, especially if the combs are additionally roughened or provided with notches «On the other hand, rounded particles of a filler added to the plastic make it possible to depending on the type and quantity, a certain amount of twisting. In all of these Cases can however nioho against each other in aehsialer Direction can be shifted.
